PostgreSQL 11.3 and 10.8

For those stuck on older versions of Postgres, I highly recommend paying the downtime to upgrade. Going from 9.x to 11 will get you a measurably large performance gain for free.

I maintain a couple of MySQL based applications. I don't really use any features outside of "standard SQL" is there a reason to switch over to Pg? I haven't used Pg before and usually default to MySQL.

It&#x27;s hard to believe that Google Cloud SQL still only has 9.6 available.<p>EDIT: Apparently 11.1 is available in beta as of April 9th.

Running 10.7 and 10.6 on two production applications with Heroku. Thinking about moving to 11 to ensure support for the long run as I rarely need to touch this and it&#x27;s very stable but would like to minimize any headaches in the future.<p>Any complications or hiccups I need to worry about moving from 10 to 11?<p>Per Heroku Docs: <i></i><i>By supporting at least 3 major versions, users are required to upgrade roughly once every three years. However, you can upgrade your database at any point to gain the benefits of the latest version.</i><i></i>

Question for PG happy users.<p>How do you manage failover and replication? At my previous job this was done by a consultant. Is this doable on a self hosted setup?<p>Thank you in advance.

Question from a Python web developer. (Django mainly, exploring Flask presently)<p>For a complex web-app, would you suggest an ORM (looking at SQLAlchemy) or a custom module with hand written queries and custom methods for conversion to python objects?<p>My app has a lot of complex queries, joins, etc. and the data-model is most likely to change quite a bit as the app nears production. I feel using an ORM is an unnecessary layer of abstraction in the thinking process. I feel comfortable with direct SQL queries, and in some cases, want to directly get JSON results from PGSQL itself.<p>Would that be a good idea, and more importantly, scalable?<p>Note : My app will be solely developed by me, not expecting to have a team or even another developer work on it.

Totally wish we could upgrade but for some reason AWS have still not implemented any upgrade path for Aurora PostgreSQL other than dump and reimport despite apparently working on it for a year...

MySQL has Galera: is there a multi-master option for Pg?<p>I know of BDR, earlier versions of which are open source, but there hasn&#x27;t been much movement with Pg 10 or 11 AFAICT.<p>We don&#x27;t do anything complicated, but simply want two DBs (with perhaps a quorum system) that has a vIP that will fail-over in case one system goes down (scheduled or otherwise).<p>Galera provides this in a not-too-complicated fashion.

impressive and .. upgrade on 10.x now in process, easily, quickly, thanks to the Postgres PGDG Debian&#x2F;Ubuntu repos .. BUT do not choose meta-package <i>postgres</i> ! Under Ubuntu at least, upgrading the meta-package postgres adds an entire new server 11+ without confirmation .. why is this tolerated.. genuinely annoying

It&#x27;s unfortunate that the official Docker images haven&#x27;t been updated yet (on DockerHub).

I&#x27;m not a database guy so have no clue, but why are there so many versions receiving support? Is there just that much legacy crap they can&#x27;t get away from, like Python?
